Is this a keyboard job related issue? see a Dr.! Workman's Comp insurance ,
Business has to pay anyhow, should cover the MD.

But I do like the GC3, integrating of bar end and a wide comfort Grip.
If i set the bar end flattish, I have my open hand palm on them,
and a really comfortable non grip..

I have my Trekking bars set up that way ..
Laying hands on rather than a 'grip' .. most of the trip.
low traffic density ..
